I spent a good three and a half years completely out of the Supernatural fandom until I got dragged back in by gifs on tumblr. It's been a bit of a roller coaster but there are some things about it that have been 100% positive. Among them is the adorable and healthy sibling-ish relationship that has developed between Dean Winchester, badass hunter (and secret nerd), and Charlie Bradbury, brilliant nerd (and secret badass).
